As I am about to watch Episode six as a reward for suffering through Marc Spector: Moon Knight (Guys, trust me, that run? PAINFUL. Horrible. DOn't read it. Wait for my summary if you love MK and want to know, but other than that? SKIP) I've been seeing in a lot of summaries of fic and posts that I try not to read as I don't want spoilers, that Jake Lockley, despite his very non latin sounding name, is some flavor of hispanic in the TV series.
On one hand, YAY! I love more spanish speaking characters!
On the other... I beg you fic writers... if you do not speak Spanish as your first language... CHECK with your nearest Spanish speaker. Who has spanish as a first language.
While there are variations depending on the country, especially with swear words, if you want to write Jake speaking spanish? You don't want him sounding like someone who just finished the first course of duolingo.
That said, if you don't have a nearest Spanish speaker? I volunteer. I will gladly beta read your spanish, or translate whatever sentences you need into spanish. That will make your Jake sound Mexican in the case of swearwords and slang, but at least he will sound like a native speaker.
